The self-crack-healing ability was systematically studied using flexural strength measurement of beams containing a semi-elliptical surface crack made by Vickers indenter. Beams of Al 2 O 3 /SiC ceramic nanocomposite with a good self-crack-healing ability predetermined for four-point and three-point

Five kinds of ceramics were used to evaluate the bending strength under three-point bending. The bending test was carried out at room temperature. The crack-healing behavior and the bending strength of the crack-healed specimens were investigated from room temperature to 1723 K. The bending strength
Alumina/SiC nanocomposites are much more resistant to severe wear than monolithic alumina. In order to clarify the mechanisms responsible for these improvements, alumina and alumina/SiC nanocomposites with 5 and 10 vol.% SiC and various alumina grain sizes were fabricated. For comparison, a 10 vol.%
